Consider the following program: What does this program do? Rewrite the code, organizing it using sound principles. Include comments and redo variable names and indentation. #include main() { int a,b,c,d; a=0; while(1) { printf("%d\n",a); printf("input?"); scanf("%d",&c); if(c==0) break; d=0; for(b=1;b<=c;b++) if(c%b =0)d++; if(d==2 || c==1) a=a+c } }

int a = 5; int b = 6; int nain(void){ printf("%d Xd \n", a, b); int a; printf("d Xd \n", a, b); return e; When this program runs it prints (at least using gcc -std=c99 program.c -o program on Vera Virtual). 5 6; e 6; This shows that the compiler implements the second int a; by initializing the local variable a to zero. Now consider this program: int a = 5; int b = 6; int nain(void){ int a-a + b; printf("d Xd \n", a, b); return e; When this second program runs it prints, perhaps surprisingly: 6 6; Based on the first program, which a (local or global) is being used to compute a + b ? Finally, consider this third program: int a = 6; int b = 5; int nain(void){ b = a + a; a = b + b; int a = a + b; int b= a - b; printf("d\n", a + b); return e; Activate Windows What integer does this third program print to the console? (at least using gcc -std=c99 program.c -o

int main() { << "Hello World!"; return 0; } Homework Exercise 1: How to Insert the missing part of the code below to output "Hello World!". How to include any additional header files that are needed. Exercise 2: How to Insert a new line after "Hello World", by using a special character How to include any additional header files that are needed. Fix any existing code (HINT: we are NOT using "using namespace std") ● ● ● ● int main() { cout << "Hello World! "; cout << "I am learning C++"; return 0; Exercise 3: Comments in C++ are written with special characters. Insert the missing parts: How to Make this a single-line comment And Make this a multi-line comment Exercise 4: How to Create a C++ program that will output your full name on one line, and your (Full name is Zaman Tonmy and college major is Computer Engineering Technology)college major on another line. How to create a multi-line comment in program and within this multi-line comment

Rewrite the program with a little bit of changes in the codes
